Back to the A/D thread.  I am selling a low cost IR interfaced A/D
through edu-calc.  the resolution is 8 bits (.4%) which is better than
most strip charts, peak reading rate is 100 samples per second.  The unit
also can control digital stuff with 4 half-amp digital outs and 4
ttl/cmos digital inputs.  a counter and pwm input/output are also
provided.  power is from a 9v battery and sleep type modes are provided
for long term data logging.  price from edu-calc is 199.95, check it out.
